EPHRAIM O. ENGBERG, 0F SALT LAKE CITY, UTAH, ASSIGNOR TO JOHN BEECI-IERPATTON, OF KENT, OHIO.

MEASURING DEVICE FOR WINDOW-SHADE MACHINES.

To all whom it may concern:

Be it known that I, EPHRAIM 0. ENG- BERG, acitizen of the United States,and a resident of Salt Lake City, county of Salt Lake, and State ofUtah, have invented certain new and useful Improvements in MeasuringDevices for \Vindow-Shade Machines, of which the following is a full,clear, and exact description.

This invention relates more particularly to measuring means for windowshade machines such as disclosed in my pending application, Serial No.388,868, filed.l-i.r1gust real, 1907. I

The primary object of the invention is to provide an attachment whichmay be readily applied to a machine of the class described, and in whicha tape or member may be made to move with one of the knives or cuttersthat trim the shade material lengthwise thereof, and which is adapted toindicate the width of the shade to be made by means of a device locatedconvenient to the normally fixed trimming knives or cutters in such away that the exact width of the shade may be quickly and easilyascertained.

A further object of the invention is to provide a simple and eflicientmeasuring attachment for determining the width of the shade to be made,which is of the form of an endless tape adapted to move past a fixedpointer or indicator, and which is so arranged that the said attachmentmay be readily applied to various machines.

The invention will be hereinafter more particularly described withreference to the accompanying drawings, which form a part of thisspecification, and will then be pointed out in the claims at the end ofthe description.

In the drawings, Figure 1 is a fragmentary longitudinal section of oneform of machine embodying my invention. Fig. 2 is a fragmentary planview; and Fig. 3 is a fragmentary front view of the attachment.

The shade machine to which the attachment is applied may be of anysuitable form. As shown the fabric 10 is adapted to pass around andbetween the feed roll 11 and tension roll 12, and from there between thesets of cutters 13 and 14L which trim the material lengthwise thereof,the fabric being attached at its forward edge to a shade roller 111 theusual manner or handled 1n any other pre- Specification of LettersPatent.

ferred way. The sets of knives or cutters 13 are supported by a bracket15, and the sets of cutters 1 1 are supported by a bracket 16, and bothbrackets may be adjusted along a transverse bar 17. The bracket 16 afterbeing once adjusted remains normally fixed; while the bracket 15 withthe cutters 13 is adapted to be moved along the rod 17 to cut the shadematerial the proper width. This movement of the bracket 15 and cutters13 may be obtained by a chain 18 which is secured to the bracket 15 andpasses around the sprockets 19 and 20, the latter sprocket being securedto a shaft 21 to which may be secured a handle, not shown, and by whichthe set of cutters 18 may be readily moved transversely of the machineas the said shaft 21 is rotated. The parts of the machine thus describedare substantially the same as in my pending application hereinbefore.referred to.

While I have not shown means for forming the shade-slat loop and alsomeans for measuring the length of the shade, these features usually forma part of the machineas manufactured, but such features form a part ofother applications, and are, therefore, not claimed herein.

To measure the fabric transversely in order to quickly ascertain thewidth of the shade to be made, I provide upon the machine frame at eachside thereof, a post 22, and on each post is arranged a rotatable spool23. Around the spools and supported thereby is an endless tape or member2a on the outer vertical face of which may be arranged suitablecharacters 25 to indicate inches, feet or part of the same, or anydesired means which would adapt the device to measure the width of shadeto be cut. A bracket 26 is fixed to one side of the tape, and thisbracket is carried by the movable bracket 15, and is so arrangedrelatively to the knives or cutters 13 that the starting point of themeasuring characters will be in alinement with said cutters, and as willbe seen, when the cutters are moved by the chain 18 or otherwise, thetape 24 will be moved therewith. The bracket 16 of the cutters 14 has apointer 27 secured thereto, and this pointer is arranged in alinementwith the cutters l4, and has its end arranged adjacent to the tape 24.By this means no matter what the position of the bracket 16 and thecutters 14 may be, the exact measnreu'ieut of the width of the shadewill be indicated, as the tape with the 1neas uring characters are movedwith the movable cutters, and the pointer 27 will thereby indicate theexact measurement, and in a much better way than if the tape werestationary and the pointer itself movable.

From the foregoing it will be seen that a very exact measuringattachment is provided for measuring the width of window shades as theyare trimmed lengthwise thereof, and that said attachment may be readilyapplied to machines of different constructions.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent 1. In a window shade machine, the com bination withmeans for supporting shade material, of cutters for trm'nnlng thematerial leugtlnvlse thereof, and a measuring derice movabletransversely of the machine with said cutters.

2, In a window shade machine, the combination with means for supportingshade material, of means for trimming the material lengthwise thereof,and measuring means movable transversely of the machine with saidtriunning means.

3. In a measuring attachment, the combination with an endless measuringtape, of a movable bracket fixed to the tape at one part thereof,cutting means movable with the bracket, and a fixed pointer past whichthe tape is adapted to move.

This specification signed and witnessed this 12th day of February A. D.1908.
